1、什么是SPA(SQL Performance Analyzer)？
SPA(
SQL Performance Analyzer)
是Oracle的SQL性能优化分析器。Oracle Database 11g 引入了 SQL 性能分析器；使用该工具可以准确地评估数据库变更对 SQL 语句的影响。SQL 性能分析器可帮助预测潜在的更改对 SQL 的性能影响。这种功能可向 DBA 提供有关 SQL 语句性能的详细信息，例如，执行前后的统计信息，提高或降低性能的语句。
SPA其实也是Oracle Real Application Testing的一个组件，另外一个组件Database Replay。SPA的原理是通过变更前对收集的STS进行执行，获取基线数据，变更后再次进行执行，然后进行对比，从多个维度比如CPU时间，I/O，buffer get等生成详细的变更对比报告。典型用法是捕捉STS，然后通过SPA生成对比报告，然后对变更后衰减的SQL调用STA进行优化。
2、SPA作用
SQL 性能分析器可用于预测和防止会影响 SQL 执行计划结构的任何数据库环境更改所带来的潜在性能问题。这些更改可以包括（但不限于）以下任何一种更改：
1）数据库升级
2）实施优化建议
3）更改方案
4）收集统计信息
5）更改数据库参数
6）更改操作系统和硬件
3、SPA测试流程
为了尽可能的减小对正式生产库的性能影响，SPA测试可以从AWR资料库中的SQL数据转化而来的SQL Tuning Set进行整体的SQL性能测试。
本次测试主要分为以下几个步骤：
在源端：
1.环境准备：创建SPA测试专用用户
2.采集数据：
a)在生产库转化AWR中SQL为SQL Tuning Set
b)在生产库从现有SQL Tuning Set提取SQL
3.导出数据：打包(pack)转化后的SQL Tuning Set，并导出传输到测试服务器
在目标库端：
1.环境准备：创建SPA测试专用用户
2.测试准备：导入SQL Tuning Set表，并解包(unpack)，创建SPA分析任务
3.前期性能：从SQL Tuning Set中转化得出11g的性能Trail
4.后期性能：在19c测试数据库中执行SQL Tuning Set中SQL，生成19c性能Trail
5.对比分析：执行对比分析任务，分别按执行时间，CPU时间和逻辑读三个维度进行
6.汇总报告：取出对比报告，对每个维度分别取出All，Unsupport，Error 3类报告
总结报告：分析汇总报告，优化其中的性能下降SQL，编写SPA测试报告
4、SPA实操
4.1、初始化数据库（源端和目标端数据库）
在进行SPA操作前，需要为数据库进行检测，目标端的数据库的表空间的大小和名字需要和源端的表空间的大小和名字一致（除去系统表空间） a、检测源端数据库的表空间
SQL> select tablespace_name,bytes/1024/1024m from dba_data_files; TABLESPACE_NAME M ------------------------------ ---------- SYSTEM 700 SYSAUX 600 UNDOTBS1 200 USERS 5 TEST 100
b、查看目标端表空间
SQL> select tablespace_name,bytes/1024/1024m from dba_data_files; TABLESPACE_NAME M ------------------------------ ---------- SYSTEM 900 SYSAUX 600 USERS 5 UNDOTBS1 55
通过对表空间的检测可以看到，目标端没有test表空间，需要在目标端创建一个名为TEST，大小为100 MB的表空间
c、目标端进行表空间创建
查看表空间的位置 SQL> col file_name for a80 SQL> select file_name,tablespace_name from dba_data_files; FILE_NAME TABLESPACE_NAME -------------------------------------------------------------------------------- ------------------------------ C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_SYSTEM_GJ3K66GF_.DBF SYSTEM C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_SYSAUX_GJ3K79OK_.DBF SYSAUX C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_USERS_GJ3K7T1V_.DBF USERS C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_UNDOTBS1_GJ3K7RWQ_.DBF UNDOTBS1 创建表空间 SQL> create tablespace test datafile 'C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\TEST.DBF' size 100m; 表空间已创建。 SQL> select file_name,tablespace_name from dba_data_files; FILE_NAME TABLESPACE_NAME -------------------------------------------------------------------------------- ------------------------------ C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_SYSTEM_GJ3K66GF_.DBF SYSTEM C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_SYSAUX_GJ3K79OK_.DBF SYSAUX C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\TEST.DBF TEST C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_USERS_GJ3K7T1V_.DBF USERS C:\ORACLE\APP\LI\ORADATA\HAPPY\LUFFY\DATAFILE\O1_MF_UNDOTBS1_GJ3K7RWQ_.DBF UNDOTBS1
4.2、导入导出数据
把源端的tns拷贝到目标端（测试不需要，如果是生产库则需要进行tns的拷贝）
同时需要注意DB link a、源端导出数据
查看directory SQL> col DIRECTORY_PATH for a80 SQL> select * from dba_directories; OWNER DIRECTORY_NAME DIRECTORY_PATH ------------------------------ ------------------------------ -------------------------------------------------------------------------------- SYS ORACLE_OCM_CONFIG_DIR /oracle/app/oracle/product/11.2.0/dbhome_1/ccr/hosts/source/state SYS DATA_PUMP_DIR /oracle/app/oracle/admin/source/dpdump/ SYS ORACLE_OCM_CONFIG_DIR2 /oracle/app/oracle/product/11.2.0/dbhome_1/ccr/state 创建directory SQL> create directory dump_dir as '/oracle/app/dump'; Directory created. SQL> select * from dba_directories; OWNER DIRECTORY_NAME DIRECTORY_PATH ------------------------------ ------------------------------ -------------------------------------------------------------------------------- SYS DUMP_DIR /oracle/app/dump SYS ORACLE_OCM_CONFIG_DIR /oracle/app/oracle/product/11.2.0/dbhome_1/ccr/hosts/source/state SYS DATA_PUMP_DIR /oracle/app/oracle/admin/source/dpdump/ SYS ORACLE_OCM_CONFIG_DIR2 /oracle/app/oracle/product/11.2.0/dbhome_1/ccr/state

4.3、源端与目标端进行SPA
4.3.1、源端操作
1、环境准备
创建SPA专用用户
create user spa identified by spa default tablespace users;
grant dba to spa;
grant advisor to spa;
grant select any dictionary to spa;
grant administer sql tuning set to spa;
2、采集数据
a)在生产库转化AWR中SQL为SQL Tuning Set
b)在生产库从现有SQL Tuning Set提取SQL
在生产端，使用Oracle SQL Tuning工具包，从AWR资料库数据中转化得到SQL Tuning Set，用于整个SPA测试流程中的SQL来源。
为了确保对生产环境影响最小，我们只对生产端采集AWR的SQL，具体采集步骤如下：
a、获取AWR快照的边界ID
set lines 188 pages 1000
col snap_time for a22
col min_id new_value minid
col max_id new_value maxid
select min(snap_id) min_id, max(snap_id) max_id
from dba_hist_snapshot
where end_interval_time > trunc(sysdate)-30
order by 1;
MIN_ID MAX_ID
---------- ----------
20 20
b、 创建SQL Set
连接用户：
conn spa/spa
如果之前有这个SQLSET的名字，可以这样删除：
EXEC DBMS_SQLTUNE.DROP_SQLSET (SQLSET_NAME => 'SOL_SQLSET_201906', SQLSET_OWNER => 'SPA');
新建SQLSET：SOL_SQLSET_201906
EXEC DBMS_SQLTUNE.CREATE_SQLSET (-
SQLSET_NAME => 'SOL_SQLSET_201906',-
DESCRIPTION => 'SQL Set Create at : '||TO_CHAR(SYSDATE, 'YYYY-MM-DD HH24:MI:SS'),-
SQLSET_OWNER => 'SPA');
查询sql set信息：
col DESCRIPTION for a50
select owner,name,STATEMENT_COUNT,DESCRIPTION,CREATED from dba_sqlset;
OWNER NAME STATEMENT_COUNT DESCRIPTION CREATED
------------------------------ ------------------------------ --------------- -------------------------------------------------- ---------
SPA SOL_SQLSET_201906 0 SQL Set Create at : 2019-06-17 23:57:05 17-JUN-19
c、 转化AWR数据中的SQL数据，将其中的SQL载入到SQL Set中
注意：过滤太多的账户会报错
从AWR中提取：
DECLARE
SQLSET_CUR DBMS_SQLTUNE.SQLSET_CURSOR;
BEGIN
OPEN SQLSET_CUR FOR
SELECT VALUE(P) FROM TABLE(
DBMS_SQLTUNE.SELECT_WORKLOAD_REPOSITORY( 20, 21,
'PARSING_SCHEMA_NAME NOT IN (''SYS'', ''SYSTEM'')',
NULL, NULL, NULL, NULL, 1, NULL, 'ALL')) P;
DBMS_SQLTUNE.LOAD_SQLSET(
SQLSET_NAME => 'SOL_SQLSET_201906',
SQLSET_OWNER => 'SPA',
POPULATE_CURSOR => SQLSET_CUR,
LOAD_OPTION => 'MERGE',
UPDATE_OPTION => 'ACCUMULATE');
CLOSE SQLSET_CUR;
END;
/
查询sql set信息：
col DESCRIPTION for a50
select owner,name,STATEMENT_COUNT,DESCRIPTION,CREATED from dba_sqlset;

------------------------------ ------------------------------ --------------- -------------------------------------------------- ---------
SPA SOL_SQLSET_201906 5 SQL Set Create at : 2019-06-17 23:57:05 17-JUN-19
d、 转化当前cursor cache中的SQL数据，将其中的SQL载入到SQL Set中
从当前cursor cache中提取：排除sys、system用户执行的语句
DECLARE
SQLSET_CUR DBMS_SQLTUNE.SQLSET_CURSOR;
BEGIN
OPEN SQLSET_CUR FOR
SELECT VALUE(P) FROM TABLE(
DBMS_SQLTUNE.SELECT_CURSOR_CACHE(
'PARSING_SCHEMA_NAME NOT IN (''SYS'', ''SYSTEM'')',
NULL, NULL, NULL, NULL, 1, NULL,'ALL')) P;
DBMS_SQLTUNE.LOAD_SQLSET(
SQLSET_NAME => 'SOL_SQLSET_201906',
SQLSET_OWNER => 'SPA',
POPULATE_CURSOR => SQLSET_CUR,
LOAD_OPTION => 'MERGE',
UPDATE_OPTION => 'ACCUMULATE');
CLOSE SQLSET_CUR;
END;
/
查询sql set信息：
col DESCRIPTION for a50
select owner,name,STATEMENT_COUNT,DESCRIPTION,CREATED from dba_sqlset;
OWNER NAME STATEMENT_COUNT DESCRIPTION CREATED
------------------------------ ------------------------------ --------------- -------------------------------------------------- ---------
SPA SOL_SQLSET_201906 36 SQL Set Create at : 2019-06-17 23:57:05 17-JUN-19
e、 打包SQL Set
DROP TABLE SPA.SOL_STSTAB_201906;
EXEC DBMS_SQLTUNE.CREATE_STGTAB_SQLSET ('SOL_STSTAB_201906', 'SPA', 'USERS');
EXEC DBMS_SQLTUNE.PACK_STGTAB_SQLSET ( -
SQLSET_NAME => 'SOL_SQLSET_201906', -
SQLSET_OWNER => 'SPA', -
STAGING_TABLE_NAME => 'SOL_STSTAB_201906', -
STAGING_SCHEMA_OWNER => 'SPA');
查看spa下用户下的表对象：
SQL> select * from tab;
TNAME TABTYPE CLUSTERID
------------------------------ ------- ----------
SOL_STSTAB_201906 TABLE
4.3.3、源端操作（导出SPA的数据）
打包(pack)转化后的SQL Tuning Set，并导出传输到测试服务器
将采集到的数据打包后，需要将其中生产库导出，并传输到测试服务器中，用于在测试数据库中进行SPA测试工作。
1）在操作系统中，导出打包后的SQL Set数据
[oracle@source ~]$ cat /home/oracle/export_sqlset_201903.par USERID=spa/spa FILE=SOL_STSTAB_201906.dmp LOG=exp_spa_sqlset_201906.log TABLES=SOL_STSTAB_201906 DIRECT=Y BUFFER=10240000 STATISTICS=NONE

2）将导出后的Dump文件传输到测试服务器
将SOL_STSTAB_201906.dmp 传输到 目标服务器 [C:\Users\li] 下：
4.3.4、目标端操作
1、环境准备
创建SPA专用用户
为了进行SPA测试，在测试数据库中创建SPA测试专用用户，避免与其他用户相互混淆与可能产生的误操作。
create user spa identified by spa default tablespace users;
grant dba to spa;
grant advisor to spa;
grant select any dictionary to spa;
grant administer sql tuning set to spa;
2、 测试准备
导入SQL Tuning Set表，并解包(unpack)，创建SPA分析任务
在进行SPA测试前需要准备测试环境，包括导入生产库中的SQL Set，对其进行解包(unpack)操作，并创建SPA分析任务。
1）在操作系统中，执行导入命令，导入SQL Set表
###win使用imp，进入到dmp的文件位置
